iOS 判断数组中数字是否连续

此时此刻没有想法，顺手写的，可能有很多bug，欢迎指正。。。

-(BOOL)suibian:(NSArray  *)array{
    
    NSMutableArray *tempArr = [NSMutableArray array];
    NSMutableArray *tempArr2 = [NSMutableArray array];

    for (int i = 1; i < array.count; i ++) {
        if ([array[i] integerValue] > [array[i - 1] integerValue] ) {
            
            NSInteger max = [array[i] integerValue];
            NSInteger min = [array[i - 1] integerValue];
            if (max - min == 1) {
                [tempArr addObject:@"yes"];
            }
            
        }
    }
    for (int i = 1; i < array.count; i ++) {
        if ([array[i] integerValue] < [array[i - 1] integerValue]  ) {
            
            NSInteger max = [array[i - 1] integerValue];
            NSInteger min = [array[i] integerValue];
            if (max - min == 1) {
                [tempArr2 addObject:@"yes"];
            }
            
        }
    }
    if (tempArr.count == 5 || tempArr2.count == 5) {
        return YES;
    }else{
        
        return NO;
    }
    
}
